MicroLED Transfer (Pick and place)

Researchers from Korea's Kookmin University developed an integrated assembly technology, that can enable microLED devices to be precisely assembled at desired positions and in desired orientations.

The new technology integrates several manufacturing processes, including mass fluid assembly, chip orientation control, defective-pixel repair and mass transfer on a single alignment platform. The researchers term the technology "Dielectrophoretic Injection-Suction Printing", or DEP-ISP.

This microLED display transfer process report provides a comprehensive look into current and future LED transfer technologies processes used for the production of microLED displays. The report covers everything you need to know about the current status of the industry.

Continuous fluidic microLED transfer process develop Pixel-Flo announced that it has raised £5.25 million ($7 million USD) in its seed round, led by Northern Gritstone with additional investment from SCVC, the Parkwalk Northern Universities Venture Fund, and HTGF.

The company say that these new funds will support its transition from laboratory development towards industrial scale-up, expanding its team and relocating to new lab and office space.

Taiwan-based MicroLED developer PlayNitride announced its financial results for Q1 2026, with 135.8 million NTD ($4.3 million USD) in revenues, down from 300 million NTD last year. The company's net loss reached 251.8 million NTD (almost $8 million), up from a loss of 51.5 million NTD last year.

A few days ago, PlayNitride also announced that its China-based subsidiary PlayNitride Kunshan has cancelled its plans to buy new microLED mass transfer equipment from Suzhou-based Yuzhu Semiconductor. The original deal (signed in February 2026) was worth $31.3 million. Yuzhu Semi will refund all payments made by PlayNitride and will not claim and compensation or restitution.

We’re pleased to feature ETRI, Korea's national research institute conducting advanced R&D across ICT, semiconductors, AI, and digital technologies, in our latest MicroLED Industry Association spotlight series.

Among its diverse research areas, ETRI is advancing microLED displays through SITRAB (Simultaneous Transfer and Bonding), a laser-assisted technology enabling high-throughput, precise, and scalable MicroLED integration.

We spoke with Dr. Kwang-Seong Choi, Assistant Vice President and principal researcher at ETRI.

Researchers from the Hong Kong University of Science and Technology (Guangzhou), led by Prof. Yunda Wang, have developed a novel microLED transfer process, based on a dynamically programmable transfer head that uses localized heating to control a polymer's stickiness.

The researchers say that this new tool's ability to selectively handle a diverse range of geometries addresses a critical bottleneck in building complex microsystems. The researchers proved their system could selectively sort and transfer functioning 45-by-25-micrometer microLEDs to form custom layouts without degrading their performance.

Korea's ETRI demonstrated a 4,000 PPI 720x540 monochrome microLED display, produced using its proprietary SITRAB bonding technology. The researchers at ETRI says that this demonstration showcases a scalable alternative to hybrid bonding for ultra-high-resolution integration.

1 µm Solder Bumps at 4 µm Pitch, enabling a 4000 PPI microLEDF

The device was fabricated by bonding microLED chips to a silicon backplane using a Cu pillar / Sn solder cap structure with approximately 1 µm bump diameter and 4 µm bump pitch. 

Researchers from Huazhong University of Science and Technology have reported a self-aligned laser transfer (SALT) based on directional photothermal regulation strategies that enables high-precision, programmable transfer of microchips or microLEDs without the need of precise laser-to-die alignment.

The researchers demonstrated multiple transfer printings of RGB MicroLED chips from different donor wafers highlight SALT’s self-aligned and batch-selective capabilities, which are crucial for efficient full-color MicroLED display assembly.

US-based signage developer Daktronics announced that it has acquired IP, equipment and technical expertise from X Display Company (XDC). It is not clear whether XDC remains an active company, or whether it has shut down after the acquisition. The company did not disclose the financial implications of this acquisition.

Daktronics says that the acquisition will enable it to integrate these technologies into its own products. The IP assets include XDC's mass transfer technologies and microLED fabrication, which Daktronics aims to use in large-format video walls and medium-sized commercial displays.
